I run the IBIS-AMI channel analysis with single & multi-board for PCIe Gen 2 signal. The following AMI models is used for simulation.
xilinx_k7_gtx_ami_rx.ibs, xilinx_k7_gtx_ami_rx.ami & xilinx_k7_gtx_ami_rx.dll
5Gbps Bit rate considered for analysis
Schematic representation with single board
Eye density results as below.
schematic representation of same path with multi-board
Same simulation parameters are used. Multi-board eye density is acceptable. But Individual board Eye density is not acceptable.
Thanks in advance
